STANLEY J. TOBIASZ, OF CHICAGO, ILLINOIS.

ASH-SIFTER.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed Matr 13, 1907. Serial No. 373,281.

To all whom it may concern:

Be it known that I, STANLEY J. ToBIAsZ, a subject ot the Emperor ofAustria-Hungary, residing at Chicago, in the county ot Cook and State otIllinois, have invented certain new and usetul Improvements inAsh-Sitters, oi which the following is a specification.

The object ot the invention is to provide an ash sitter so inclosed asto prevent the escape ot dust or dirt and at the same time enable theready insertion oi raw ashes and the removal ot the sitted ashes andcoals.

The invention consists in the features ot construction and combinationot parts hereinaiter described and claimed.

In the drawings, Figure 1 is a trent elevation of the ash box showingthe door removed; Fig. 2 a sectional elevation showing the side ot thesitter box; and Fig. 3 a perspective view ot the sitter box.

The ash box, as a whole, is in the iorm ot a rectangular box 4, havingside walls 5, a rear Wall 6, a root 7, and a front cross wall 8. Thecross wall is ot a size to provide an upper opening, closed by means ota hinged door 9, and a lower opening into which is entered a drawer 10.Immediately above the drawer the walls ot the ash box are provided withastrip ot metal 11, in the torm ot a chute adapted to divert the sittingsinto the drawer. Within the ash box is located a rotatable sitter box 12comprising sides 13, each ot which has a curved upper portion 14, andbetween the curved upper edges ot the side walls ot the box is stretcheda screen 15. The rear end ot the screen is secured to a cross rail 16,and the tront portion ot the screen is in the torm of a door 17 securedto the main portion by means of rings or hinges 18. The lower iront edgeot the door portion is secured to a door cross rail 19, which, when thedoor is closed, is immediately above and in alinement with a xed trontcross rail 20, to which the door section is secured by means ot a hook21. In addition to the tront and rear cross rails the sides are securedtogether by means ot cross sills 22 extending across the bottom ot thebox; and inside ot the side walls and extending trom end to end ot thespotter box are downwardly sloping inner side walls 23, the lower edgesot which rest upon the cross sills 22, and these inner side walls servethe double purpose ot bracing the main side walls and also providing asocket tor the reception ot a tapered pan 24, the formation ot whichpermits it to be wedged tightly in place between the sloping inner sidewalls. The sitter box is mounted on trunnions 25 and 26 which extendthrough the side walls ot the ash box, and the trunnion 26 is extendedand has secured thereto a handle 27 which permits the sitter box to berotated.

In use, when it is desired to sift a quantity ot ashes,

the hinged door 9 ot the outer sitter box is opened, and thereafter thehinged screen door 17 is interlocked and litted back, which permits apan ot ashes to be inserted into the interior ot the sitter box andwedged in place between the sloping or converging side walls 23. Atterthe screen door has been fastened down and the main door ot the ash boxclosed, the sitting operation is pertormed by turning the handle androtating the sitter box. This operation serves to agitate the ashes, and

with every revolution the tine particles and dust are dropped throughthe screen, the unburned coals remaining within the pan ot the sitterbox. After the sitting operation is completed, the pan can be removed,and likewise the lower drawer 10, which contains the Sittings, can beremoved and emptied in preparation tor turther operations.

The invention is one which permits the easy insertion ot ashes carriedin a pan and undisturbed prior to the closing ot the ash box door. Thisobviates the creation ot dust incident to ordinary ash sitters in whichthe ashes are dumped out ot a pan or back into the sitter prior to theclosing ot the same. In the present instance, no disturbance is createduntil the ashes are iinally deposited in position to be sitted and thedoor shut. At the same time the same pan which serves tor thetransportation ot the unsitted ashes will serve tor the carrying ot thereclaimed coals, which renders the operation simple, easy and unattendedby any objectionable tea-tures.

What I regard as new and desire to secure by Letters Patent is:

l. In an ash box, the combination of an inclosing box provided with adoor, and a rotatably mounted sifting box comprising flat side wallsprovided with curved upper edges, a screen connecting said curved upperedges, cross connections for the bottom and ends of the fiat side wallsof the box, downwardly sloping inner side walls constituting bracesbetween the outer side walls and the bottom cross connections, and anash pan having downwardly converging side walls adapted to be wedgedinto place between tlie inner sloping side Walls, and a handle forrev0lving Athe sitter box, substantially as described.

2. In an ash box, the combination of an inclosing box provided with adoor, and a rotatably mounted sifting box comprising flat side wallsprovided with curved upper edges, a screen connecting said curved upperedges, a portion of said screen being hinged to provide a door, crossconnections for the bottom and ends of the lat side walls of the box,downwardly sloping inner side walls constituting braces between theouter side walls and the bottom cross connections, and an ash pan havingdownwardly Converging side walls adapted to be wedged into place betweenthe inner sloping side walls, and a handle for revolving the sitter box,substantially as described.
